Deductions & credits

2020 earned income: $2400.

2019 JOINT earned income: $31,000 (too high) but if only 1/2 of that amount is my PYEI from that joint return, then it is $15,500.

 

You see my reason behind seriously wanting to know what the law means when it refers to prior year 'earned income of the taxpayer' I am an individual taxpayer. I am no longer part of that 'joint' 'community' and I'm trying to figure out if my 'look back' is only supposed to look at my portion of that joint community earnings from when I was still married.
